CONCRETE RAILW'AY-TIE.

To all whom it may concern:

Be it known that we, TVILLIAM J. LANK- ronn and IVALTER H. CHAIPELL, citizens of the United States, residing at Chanute, in the county of Neosho and State of Kansas, have invented certain new and useful Improvements in Concrete Railway-Ties, of which the following is a specification.

This invention seeks to provide an improved concrete railway tie that embodies a plurality of sections in endwise alinement adapted for being readily assembled or connected in operative condition and which are especially designed for convenient connection with means tending to so connect the body sections that the ready removal and renewal of the said parts may be expeditiously and practically accomplished.

More specifically our present invention has reference to improved features relating to the special type of concrete tie disclosed in our copending application, Serial No. 420,605, filed October 30, 1920, of which this application is a divisional part, and our said present invention embodies certain peculiar features of construction and modi fieations of the form of rail tie disclosed in our copending application, all of which will be fully explained in the following detailed description, specifically pointed out in the appended claims and illustrated in the accompanying drawing in which:

Figure 1 is a top plan view of our present construction of concrete tie, the longitudinal and transverse reinforce members hereinafter referred to, being indicated in dotted lines.

Fig. 2 is a partial longitudinal section of one end of our present construction of concrete tie.

Fig. 3 is a transverse section thereof taken on the line 3-3 on Fig. 1.

Figs. 4 and 5 are respectively a top and a bottom perspective of the tie plate hereinafter referred to.

Fig. 6 is a detail view of a modification of the rail brace member hereinafter mentioned.

In the drawings, in which like numerals designate like parts in all of the figures and referring more particularly to Figs. 1, 2 and 3, the body portion of the tie consists of two half sections 1-1 that are disposed end to end and in longitudinal alinement and, in the practical development of our concrete Specification of Letters Patent. Patented rhllg. 16, 1921. Original application filed October 30, 1920, Serial No. 420,605.

Divided and this application filed March Serial No. 451,967.

tie, the outer end of each of the sections 1 preferably has a clover leaf or lobe shape, as shown in Fig. 1, the opposite sides and end faces of the body being vertical and provided with panels or recesses for the convenient handling of the said body sections, when placing them in their cooperative position or removing them when neces sary.

Each tie section 1 has a countersunk recess 3 at its inner end and such recesses 33, when the tie sections are placed end to end, form a space into which is received a cushioning block 4 whose purpose is to take up and intercept vibration of the tie body and avoid the effect of rigidity of the tie.

In our present construction of tie, the

rails 1010 do not rest directly upon the top of the tie but seat on metal plates 5 which are hereinafter termed tie plates, the application of which and the means for holding them securely upon the top of the tie section 1 and the clamping devices that cooperate therewith, being best shown in Fig. 3.

By referring to the said Fig. 3, and to Figs. 4 and 5, it will be noticed the plate 5 has a central recess 50 at the outer edge thereof and at the opposite edge it has a centrally disposed aperture 51, the purpose of which will presently appear, it also having along the said opposite edge, other apertures 66 each of which is designed for receiving a clamp bolt 7, the latter serving as spikes for clasping over the adjacent base flange of the rail, as is best shown in Fig. 2.

Each bolt 7 has an angled portion 70, at its lower end. for engaging with a reinforcement plate which extends under a draw rod 9 whose outer end adjustably carries a clamping device adapted for engagement with the base flange and the web of the adjacent rail, as will he presently more fully explained.

In the present arrangement of our cement tie and rail clamping means, cushion members 11 are also included that seat under the plates 5, as shown in Figs. 2 and 3, and the outer edges of the said members are shaped to straddle the clamping device on the outer end of the draw rod 9, as is clearly indicated in Fig. 2.

The inner ends of the cushion members are secured by the spike bolts 7 that pass down through the said inner ends thereof, which ends are securely held down by the tie plates 5 and the upper clamping ends 12 of keepers 12, presently further referred to, and the outer ends of the said plates 11 are notched to straddle the rail clamping ties on the outer end of the rod 9, as shown in dotted lines,-Fig. 2.

The keepers 12, before referred to, are embedded in the cement sections and each ofthe said keepershas an inturned hook 12 that fits over the outer edge of anadiacent tie plate 5 one being located ateach side of the rail clamping device to be presently explained, the said keepers 12 in addition to holding the plate 5 serving :to also avoid spalling of the concrete at the outer edges of the said tieplatesi In the preferred arrangement of the rail clamping means, two opposite draw rods 9-.-9 arejoined by a turn buckle connection 1.7, as shown and described, and the outer end of each draw rod 5) is provided with a rail clamping device, oneof such devices beingshown in detail in Fig. 2, which illustrates the said device as consisting of a combined clamp and anchor device which includes a basethat seats and has longitudinal adjustment within the .outer end of the groove or channel 16 that extends through the end of the tie, the ifit of the clamp base within the groove being such that the clamp is held against tendency of lateral displacement. y

The base of the clamp 30 has a passage for slidablv engaging the outer threaded end 96 of the draw rod 9 and it is adapted to be closely drawn-up against the face of the adjacent rail end by an adjusting nut 3-3.

While we prefer to use two draw rods 9i-.-9 with a turnbuckle connection 17 as is shown and described, it should be mentioned that when the rail, clamp devices 30 are arranged as described and shown but asingle draw rod-9, extending practically the full length of the tie may be used and the turn buckle devices 17 may be dispensed with since the combined clamp and anchor devices 30 will keep the rails from tilting or spreadinstead of arranging the combined clamp member 30, asshown {in Fig. 2, the said rail engaging means may be as shown in the slightly modified arrangement illustrated in Fig. 6, which shows a supplemental brace member 19 which is adapted for engaging the rail web directly under the head or tread portion .thereoafland which includes a pendcut or base portion 19 that is apertured to slidably fit upon the threaded end 96 of the draWba-r .9 and which is held up to the clamping 1position, w-ith the clamp 80, by a nut 33, as shown.

In the practical application of our pres ent form of rail tie, the same is provided with headed studs for engaging with slot- ,ted ways 61 in the, vertically adjustable application, the tie ends may be further reinforced by vertical andhorizontal tie rods, as fully explained and shown in our copcnding application before referred to.

It is understood that the specific arrangement of the parts that constitute our present type of rail tie and rail clamping means may be further modified or varied without departing from the scope of the appended claims. 1 r
